Glossary Architectural Mesh

„aw“, „as woven“HAVER Architectural Mesh is manufactured from high-quality wires on weaving machines which were developed and assembled by Haver & Boecker’s engineering specialists.

Acoustic FleeceSound-absorbing material, which can be concealed with architectural mesh. Can also be integrated directly into cassette systems with architectural mesh.

Aperture Width (w)Aperture width, w, is the distance between two adjacent warp or weft wires, measured in the projected plane at the mid-positions.

Architectural MeshWoven wire mesh for the use in architecture. In the selection of the material, the production and the processing as well as the fastening, the demands of an optical application as well as the loads have to be taken into account.

Cable MeshA wire mesh, which is made in the warp direction of rope, also called cable mesh. It is flexible in direction of the cables and robust in direction of the rods. Due to the flexibility in the direction of the cables, cable meshes can be deformed into narrow radii.

CalenderingThe woven wire mesh is rolled to a specified thickness, simultaneously producing a smooth surface. For fine mesh, this can also influence the filtration criteria of the mesh.

Ceiling Lining / ceiling claddingCeiling linings are non-load-bearing ceilings, which are attached to a substructure. With different ceiling systems, measures for thermal and sound insulations can be connected. Depending on the system you can distinguish between surfaces, sheets or grid structures.

CertificationHaver & Boecker's quality management system is certified according to DIN EN ISO 9001:2008. The company's automotive area is also certified according to the especially high standards of ISO TS 16949.

Daylight SuitableMedia façade systems are suitable for daylight, if the content can be presented in full daylight.

Digital PrintingBy digital printing, complex graphics and pictures can be applied to architectural wire mesh. Even photos and very detailed pictures can be displayed. The visibility depends always on the selected wire mesh as well as the viewing distance. For exterior applications (e.g. on facades) an additional UV-resistant protective coating is used to protect the images against environmental impact.

Facade CladdingThe facade cladding is attached in front or to the supporting wall construction of a building. Different materials can be used so that a variety of design possibilities are available for the exterior wall cladding. The exterior envelope of a building has not only optical function, a façade cladding can also be important for thermal insulation, sun protection or fall protection.

Fine Wire MeshFine wire meshes are mesh types which are produced from wires with a very small wire diameter. The classification as fine mesh is essentially dependent on the particular application. Whereas for industrial applications mesh types with an aperture < 0.2 mm are referred to as fine wire meshes. For architectural applications, clearly larger mesh types are also called fine mesh. For architectural applications, all types of wire meshes are classified as fine mesh, which are very sensitive to mechanical stresses. Due to their small mesh width and the filigree wires they are more suitable for indoor applications.

Fire ProtectionAll preventive measures, which prevent formation or spreading of a fire, are summarized under the term fire protection. In this context, the use of a wire mesh is helpful because it can contribute to a smoke extraction with correspondingly large open area.

Flat Wire MeshWire mesh, which is made of flat wires or split strip. Due to the width of the wire, flat wire meshes have a large surface area and a lighter weight compared to round wire meshes with the same open area.

The g-value represents the permeability of transparent components with regards to the energy transport. It indicates the percentage of solar energy, which penetrates through a component (e.g. window). For example: A g value of 0.6 means that 60 % of the solar energy enters the interior. The rest of the radiated energy is reflected or absorbed. The entire façade system has to be assessed for the use of wire mesh as sun protection in combination with a glass façade.

ISO 9001:2015DIN EN ISO 9001:2015 specifies the requirements for a quality management system (QMS). A certification process provides proof of compliance. Haver & Boecker was one of the first companies to be certified according to DIN EN ISO 9001 as early as 1997.

Intermediate MountingThe maximum resulting loads on the substructure as well as the possible deflection of the mesh are reduced by intermediate fixings. Usually, an intermediate mounting is recommended at the height of a floor slab (about 3 - 4 m).

LEEDLeadership in Energy and Environmental Design: 1998 Developed classification by the U.S. Green Building Council for ecologically construction. Defines standards for environmentally friendly and sustainable building.

Light Emitting AngleThe light emitting angle defines the emission range of an LED in which at least 50 % of the maximum brightness of the light source / LED is achieved.

Media FacadeOuter envelope of a building, which can be used for the presentation of visual representations (pictures, videos, text, ...). By using the media façade IMAGIC WEAVE® a transparency can be created which provides a view from the building as well as a corresponding light incident inside the building.

MeshA wire medium produced in a weaving process, which is used for technical and design applications.

Mesh GeometriesThrough different mesh widths and geometries as well as different weave types, different structures of a wire mesh can be achieved. That offers architects and designers a variety of design possibilities.

Mounting SystemsVarious fastening systems have been developed for the application of architectural mesh elements. For each project the suitability and feasibility of the selected solution has to be checked individually.

Non-ferrous MetalCopper and Copper based Alloys as copper, brass and tin bronze referred to as non-ferrous metals. Wire mesh can basically made of a wide variety of metals. Nevertheless, with many metals, you should be careful with their optical characteristics.

In the case of non-ferrous metals, it must be ensured that their surface can be tarnish under atmospheric conditions, so that a homogeneous appearance is no longer guaranteed. Furthermore, the strength of the material is limited according to the installation situation.

Alternatively, stainless steel mesh can be provided with a corresponding metallic painting.

Open FacadeIn the planning of car parks, the opening proportion of the façade cladding plays an essential role in ensuring adequate ventilation of parking garages. In order to achieve an "open facade", a wire mesh is often used with a correspondingly matched open surface.

PaintingApplying a colorless or colored lack to an object or a surface. Architectural mesh can be painted in almost any color. Customized individual logos and patterns can be realized on a façade or wall cladding. Also metallic effects can be achieved with a painting.

Perforated PlatePerforated plates are made from, for example, stainless steel, aluminum, zinc, steel and brass. In practice often referred as perforated metal.

Pitch (p)The distance between the middle point of two adjacent wires or the sum of the aperture size w and the wire diameter d.

Plain WeaveType of weave wherein each warp wire alternately crosses over and under each weft wire.

Powder CoatingProcess for protecting the metal surface from corrosion. Using an electrolytic process, dry powder is sprayed onto the grounded stainless steel mesh and melted in a kiln. The resulting uniform coating film is particularly robust and dirt-repellent. High quality powder coatings are available in almost all RAL colors. Due to its stability, this method “fixes” the wire mesh and thus the mesh loses its flexibility. For this reason, a painting is often used for designing wire mesh.

PreloadThe preload is the initiated tension during the installation. For the interpretation of the substructure, the maximum occurring in operating load is decisive, which is to be determined individually for the needs of a project.

Protection Class IP67Protection class which indicates the suitability of electrical equipment for various environmental conditions. IP67 is dust-proof and suitable for temporary submersion.

Sintering / AnnealingThermal pretreatment for the processing of metal mesh.

SMT-LEDA SMT LED is a possible design of LEDs. An LED is an electronic semiconductor element which emits light once a specific voltage gets applied (LED -> Light Emitting Diode).The connection contacts are led to the outside side as wire bones. The designation THT (Through Hole Technology) stands for the type of assembly of the components. The contact wires are guided through the contact holes of a circuit board and soldered on the rear side. Typically, boards are only equipped with THT components on one side.

Stainless SteelSteels of special purity are referred to as stainless steels. In many cases, however, corrosion-resistant steels (stainless steel) are also grouped together. Stainless steels are available in various alloys which should be chosen depending on the ambient conditions.

Stainless Special Steel (Edelstahl rostfrei)Under this designation, corrosion- and acid-resistant steel grades are combined.Stainless steel is protected against corrosion by a thin chromium oxide passivation layer. Oxygen from the atmosphere combines with the chrome of the stainless steel and forms the chromium oxide film, which protects the surface of the stainless steel.

Stainless Steel AISI 316This grade of stainless steel is the most used for architectural mesh. It is characterized, among other things, by its good corrosion resistance (corrosion resistance class III).

Other terms: V4A; Stainless steel 1.4401

Stainless Steel MeshWire medium made of stainless steel and produced in a weaving process. It could be used for technical and design applications.

Sun ProtectionSunshade made of architectural wire mesh for windows and other glass surfaces ensures that the sunlight cannot penetrate so much in the interiors. At the same time it provides efficient heat protection and optimizes daylight economy.

Suspended CeilingsSuspended ceilings are second levels under existing ceilings. A suspended ceiling can be used to carry out sound insulation measures or to eliminate optical ceiling problems such as uneven surfaces or visible cables.

Tensile TestTest method for the characterization of wires and wire meshes:The tensile test is used to determine the mechanical properties of metallic tensile specimens, such as yield strength, tensile strength, maximum load, elongation, among other things by axial tensile stress until fracture. HAVER & BOECKER tests web wires and wire mesh on the most modern, computer-controlled universal testing machines.

THT-LEDA THT LED is a possible design of LEDs. An LED is an electronic semiconductor element which can emit a specific voltage light (LED -> Light Emitting Diode). The connection contacts are led to the outside side as wire bones. The designation THT (Through Hole Technology) stands for the type of assembly of the components. The contact wires are guided through the contact holes of a circuit board and soldered on the rear side. Typically, boards are only equipped with THT components only on one side.
